Thank you. I will run it with raised airflow in the morning and report back.

Hello,
I have a CTSV with BTR Stage 1 Cam (223/238 .610"/.585" 120+6), headers, 2.4 upper pulley, and an LS7 TB when the temps get cold (below 50F or so) I get a surging idle a few seconds after...
Your tune would help. Do you have a IAT or ECT sensor fault? Fuel pressure is at Min pressure. Not saying that that is the cause of the pressure spike but maybe you have another faulty sensor...
Here is one from the quarter mile with street tires.

Why dont you post one yourself? Youll get feeback if someone sees something wrong.

Set plug 6 to .32 and reinstalled it seems better also added more fuel. Seems to be back to normal.
Plug seemed to be ok, No weird color, no cracked porcelain, the gap was larger than I remember setting it to. I thought I set them all to 0.32 this one was about 0.38.
Just started tuning the 50% E85- No added timing- just working fueling first

Yes, It doesn't feel like a clean pull but I dont want to do any more until I figure this out. In that same log I got 46 misfires on cyl 6 so Im pulling the plug now. Could the KR be the result of...
I have a CTS V that is having a weird issue where occasionally the boost will spike in the middle of the RPM range. I have never seen this before, any ideas?
Please see the attached picture, the...
Can you log fuel pressure?
Are the cams in there park positions at idle? Also, In EGR areas is the intake cam advanced and exhaust cam retarded with close to maximum overlap?

Testing: Increase intake...
Has anyone played with the cam tables yet? Tried adjusting them, but wasn't able to get any conclusive results. Looks like the cams start at zero when key on engine off, are a 23 degrees intake 9...
I don't think it would be related... does it start working again if you re-enable Maf?
Since we have no idea what you've done already. Raise peak and max torque tables by 5-10 % and see if you get more boost. Also,

I had this happen before, if I remember correctly it was because I raised the pressure delta factor to high. These ECMs seem to like making small changes to the tables rather than raising the values...
+1 Post your file if you would like a second pair of eyes to look things over. Your results seem low you should be able to pick up more than 2-5 hp with a tune.
To raise your desired try raising your pressure ratio max table. For the PE issue check cat over temp and turbo over temp.
Cool! Thanks for trying it and posting results. Great dyno, really close to 200 crank.
Depending on where you installed you the sensor, did you greatly reduce you delay volume? If your using cruze injectors you should be able to copy the data straight out of the cruze
I think it is your PE table. Just because it commands 13 AFR in the midrange does not mean that is what the engine is actually seeing. I run about the same airflow and run stock PE enrich table...
Never tried it but I really don't think it will hurt anything. You cant get negative power from the engine anyway.
Sorry have not tired to raise it but did up the delta pressure when going high flow a little with no noticeable effects. Ive read that they command a lower fuel pressure at idle and low speed...

Good Luck!
GM seems to have started tuning for the fuel customers were actually using in the US. Most pump gas contains up to 10% ethanol, as a result the stoich is lower than pure gasoline. Unless you are...
I am trying to manipulate desired boost, currently desired boost targets 219 kpa from 3000-5800 rpm then rises steadily to a max of 247kpa at readline. I want it to desire 240 kpa ~ 20 psi from...
